Abstract : The patent concerns an apparatus for attaching removable photochromic goggles to a conventional crash helmet. The apparatus includes a post on one side of the helmet adjacent the face opening and an over-center latch on the other side of the helmet which engage apexes of triangular eyelets formed in straps extending from the distal ends of the goggles. The over-center latch has a lever with a camming surface formed thereon, notched to retain the apex of one of the eyelets and pivoted such that upon turning of the lever aftwards the notch is moved aftwards, stretching the straps, for vertically locating the goggles in front of the wearer's eyes.
